Novi Vinodolski is a coastal town with a rich, cultural history. This is also shown by the fact that the Vinodol Code and one of the most famous Croatian families, the Mažuranić family, originate from Novi Vinodolski. But, the city is also known for its carnival customs and its citizens who do not allow valuable customs to be forgotten. Novljanski mesopust is a real play that has its place and time of action and actors. In Novi Vinodolski, customs live not only through their implementation, but also through various institutions that keep the most valuable evidence of the existence of the Novljanski mesopust and who work hard to make the customs still alive today. The aim of this undergraduate thesis is to show the folk customs of Novi Vinodolski and raise awareness of how important folk customs really are, since we are living in a time where young people forget their tradition, and for that reason, the tradition eventually disappears. The undergraduate thesis is conceived in eight main chapters in which the Novljanski mesopust will be presented through an oral folk drama, through folk customs that take place during the carnival, through žitak. Furthermore, the Novljanski mesopust and Novljanski folk customs will be presented through the Novljansko kolo, the Novljanski traditional costume design and through institutions that preserve and maintain the cultural heritage of Novi Vinodolski.
